DE ELD'N E. HAYNER STOP DEVICE FOR ROLLER SKATES Flled March 24 1949 May 1, 1951 Patented May 1, 1951- UNITED STATES PATENT OFFIE STOP DEVICE FOR ROLLER SKATES De Eldon E. Hayner, Floral Park, N. Y.

Application March 24, 19-49, Serial No. 83,130

V 9 Claims.

This invention relates to roller skates, and in particular to a stop device applied to the toe portion of the skates to facilitate and increase the range of use of the skates in performance.

A particular object of'the invention is to provide a flexible and adjustable stop means in which excessive wear on the rubber friction pad is prevented and one which will not mark the floor of the rink when the skater performs in gyratin motions with the stop in contact with the floor.

Other objects include the use of a stop of flexible nature which permits complete contact with the floor throughout the area of the stop so that a positive grip of the stop with the floor is afforded when the skater performs a jump or stop action; to provide for rotary adjustment of the stop so that the turning action thereof may be readily varied; to provide a stop device that can be applied to any roller skate; and to provide a device of the character referred to which offers a flexible, adjustable and firm stop to facilitate quick stops, jumps and spins.

With these and other objects in view, the invention comprises certain constructions hereinafter described and then particularly pointed out in the claims, and a preferred embodiment of my invention is illustrated in the accompanying drawing in which:

Figure 1 is a View in side elevation showing the stop device as applied to the toe portion of a roller skate;

Figure 2 is a view in front elevation of the skate stop shown in Figure 1;

Figure 3 is an enlarged view, partly in section, of the stop as it appears on the skate in Figure 1;

Figure 4 is a section taken on the line 4-4 of Figure 3 and shows the mounting of the parts;- and Figure 5 is an enlarged side view of a stop device having variations of construction from the stop illustrated in Figure 1.

Referrin to the drawing in detail, indicates a roller skate body having the usual wheels H and wheel carriers [2. To the toe portion I3 of said body is attached, by any suitable means, a bracket I4 having an arcuately depending portion slotted as at IE to hold for adjustment, a stop assembly indicated generally by the numeral IT. The inner and outer faces of the segment [5 arecorrugated as at l8 to fit like corrugations in the faces of an opposing limit nut l9 and a saddle ring 20 carried by a bolt 2| passing through said slot I6. The bolt also carries a lock nut 22 which coacts with the limit nutl9 through 5 z ring-20 to permit radial or swinging adjustment of the stop with respect to the segment I5 and also raising or lowering movement of the stop with respect to the floor. I Y

The stop l1 further consists of a cushion sleeve 23, made of rubber, plastic or any suitable mate rial covered at its upper end by'a cup disk .24, and supported at its lower end in a recess 25 formed in the face of an upper ball race plate 26. The latter is spaced from a lower ball race cup 21 by the ball or other roller bearings 28. It is not essential to the invention that the antifriction bearings be used, as plain plates or bear-' in disks having relative rotation can be employed if desired. The race cup 21 is shapedto provide a depending annular flange 28Afrom which prongs 29 are forced inwardly to be embedded in the rubber stop cushion 30 that is molded or otherwise secured in said cup. The top of the cup 2'! is also shaped to provide inwardly directed prongs 3| which coact with the prongs 29 to securely anchor the stop block or cushion in place in the cup. The-cushion or rest 30 is provided with an axial recess 32 and a bore for passage of the bolt 2| which is provided with a slotted head 33 at the lower end and a thread at the upper end, the bolt passing through suitable openings in the various partsof the stop structure to hold the latter assembled.

It is evident, by adjustment of the members I9, 20 and 22, that the bolt and its associated stop parts can be swung to any oblique position desired and that by longitudinal adjustment of the bolt itself the stop structure may be raised and lowered with respect to the skate.

In the modified form of the invention shown in Figure 5, the toe portion 35 of the skate body has secured thereto, as by screws 36 or the like, a bracket 31 having a base portion 38 and an obliquely disposed tubular extension 39, in the threaded bore 40 of which is mounted for adjustment the threaded end of a bolt 4 I. The bolt mounts the stop parts including a lock nut 42, a cup disk 43, a cushion sleeve 44 interposed between the disk 43, and an upper ball race plate 45; and the rubber stop cushion 46 carried in the race cup 41. The cushion or stop block 46 has an axial cavity 48 in which the slotted head of the bolt is protected. In order to vary the angular position of the stop structure, use is made of a wedge block 49 of tapered shape which fits between the body of the skate and the face of the bracket 31.

The various adjustments may be accomplished by compression of the sleeves 23 or 44 under stop that can be attached to any skate or extension plate thereof, permits the rubber friction stop to make complete flat contact with the floor to give the skater a positive hold needed for a jump, stop or gyratory maneuver, prevents marking of the floor of the rink, and may be adjusted for rotary tension as the skater sees fit by the simple adjustment of the bolt. If desired, the bracket l4 may be made integral with the skate portion l3.

My invention is not to be restricted to the vprecise details of construction shown since various changes and modifications may be made therein without departing from the scope of the invention-or sacrificing the advantages to-be derived from its use.

What I claim is z 1. The combination with-a skate,oi a stop device including a brackethaving a segmentalportion for attachment to the toe portion of the skate, a floor engaging pad, means for pivotally mounting saidlpad, and means for'adjusting said mounting means arcuately along said segmental portion.

2. The combination with a skate, of a stop device including a bracket for attachment to the toe portion of the skate, a floor engaging pad, means for pivotally mounting said pad, means for adjusting said mounting means obliquely, and means for adjusting said pad in a direction toward and away from the skate.

3. A skate stop device of the character set forth in claim 1 in which the pivotal mounting means includes a bolt, an anti-friction bearing supportedon said bolt and means for securing the pad to said bearing.

*4. A skate stop device of the character set forth in claim 1 in which the pivotalmounting mean includes a bolt having a threaded portion, meansfo'r securing the bolt to the bracket, an

anti-friction bearing supported on said bolt, means for securing the pad to said bearing and means for varying the frictional resistance of said mounting means to pivotal movement.

5. A skate stop device of the character set forth in claim 2 in which said pad adjusting means includes a bolt, means for fixing said bolt in the bracket, a compressible member between the pad and said bolt fixing means and means for adjusting the bolt axially.

6. A skate stop device including a bracket for attachment to the toe portion of a skate, a bolt, means for securing the bolt to said bracket, a plurality of disks carried by said bolt, a plurality of pad members associated with said disks, one of-sai'd pads constituting a floor engaging stop and an anti-friction bearing between said disks.

7. A skate stop device including a slotted bracket, a bolt having a threaded end extending through said slot, lock means for securing the bolt to the bracket .in adjusted. position, a plurali-ty of bearing disks on the bolt a stop padonone of said disks, antiefriction bearings between the disks .and a yieldable cushioning. means on said boltv between said bearing disks and said lock means.

8. The combination with a skate of a. stop device including a bracket, a bolt axially adjustable in saidbracket, a floor engaging stop on the lower end of the bolt, means for revolvably mounting the stop on the bolt, and yieldable means for cushioning a movement of the stop along the bolt under floor engaging pressure.

9. In the combination set forth in claim 8 wherein said stop mounting means includes an anti-friction bearing and means for adjusting thebolt obliquely.
